Adaptive control for a class of nonlinear uncertain systems based on fuzzy logic system

We suggest a nonlinear controller and adaptive law design method by using fuzzy logic system for a general class of nonlinear uncertain systems with unknown bounds of uncertainties. The robust controller and adaptive laws obtained ensure the states of systems controlled uniformly ultimately bounded (UUB) and corresponding parameter errors converging to a neighborhood of zero. The simulation results obtained show the validity of the method in this paper.
